Sorry, once again.
Hello, everyone
My software environment is the following:
----------------------------------------------------------------------------
-----------------------------------------------------------
Win7 64bit Janpanese
postgresql-9.0.11-1-windows-x64.exe
postgresql-9.0-801.jdbc4.jar
Seasar2 (a j2ee framework popular in Japan, including DI ,AOP, Struts, O/R
Mapper,etc.)
----------------------------------------------------------------------------
------------------------------------------------------------
When I used the O/R Mapper of Seasar2 to do a simplest insert SQL statement,
I saw the record had been inserted into DB,
But in the log file of C:\Program Files\PostgreSQL\9.0\data\pg_log,
the following log information were also produced.
2013-05-20 10:48:01 HKT postgres changdb LOG: クライアントからデータを受信
できませんでした: No connection could be made because the target machine
actively refused it.
2013-05-20 10:48:01 HKT postgres changdb LOG: クライアント接続に想定外のEOF
がありました
Sorry, it is in Japanese, and I will translate it into English.
クライアントからデータを受信できませんでした -> could not receive data
from client
クライアント接続に想定外のEOFがありました -> unexpected EOF on client
connection
In fact, whenever I execute any insert/update SQL statement, it always
appears.
My customer asked that it must be made to disappear.
I have googled, but can’t find any useful advice.
I have shutdown the firewall of Win7 and
<http://www.iciba.com/anti-virus_software> anti-virus software in My PC. But
This is no use.
This page said that these error reports when the connections are closed
uncleanly, without a proper backend close message.
http://grokbase.com/t/postgresql/pgsql-general/1137bke7ew/unexpected-eof-on-
client-connection-vs-9-0-3
I think it is the most possible reason. But I don’t know how to fix it.
Anyone can help me. Please.
Thanks
